QuestionI have a 1970 Monte Carlo that has been garaged in Texas since 1982. The gas was left in the tank. Can I used an additive to clean the gas or do I need to remove the tank and the old gas. I have not tried to start the car yet. Any pointers on proper steps to take before trying to turn the engine over?
AnswerHi Paul:
I answer this question a lot...
Any car that won't be driven for 12 to 18 months, should be
prepared for dry storage. Dry storage is when you drain ALL
fluids from the car and put it up on blocks (e.g. remove the tires#.
This car has been sitting for 28 years! I'm guessing the oil and
transmission fluid look like gel. In any case, the first thing to
do is replace ALL fluids #e.g. oil, transmission, brakes, anti-freeze,
power steering and yes, gas. Dump everything. Also check the plugs
for corrosion. If the car was kept in a dry environment, then the
plugs and other ignition and electric system components should be fine.
Turn her over only for a few seconds the first time you try to start her.
This will check the pistons, lifters and valves to make sure they have not frozen.
After a few try at short cranks, if everything appears to move okay, try to start her.
